Summary
The Wallstent endoprosthesis effectively recanalizes ureters blocked by pelvic cancer, maintaining patency throughout patient survival. This study shows high long-term stent patency in obstructive uropathy cases.
Area of Science:
- Urology
- Oncology
- Medical Devices
Background:
- Malignant pelvic disease frequently causes obstructive uropathy, leading to ureteral obstruction.
- Ureteral obstruction can cause significant patient morbidity and impact quality of life.
Purpose of the Study:
- To evaluate the efficacy and durability of the self-expanding Wallstent endoprosthesis for ureteral recanalization.
- To assess stent patency in patients with obstructive uropathy secondary to malignant pelvic disease.
Main Methods:
- Retrospective analysis of 19 Wallstent insertions in 14 patients with malignant pelvic disease.
- 100% patient follow-up to assess stent patency and duration.
Main Results:
- High stent patency was observed, with only one case of failure.
- Stent patency persisted for the duration of patient survival, with longest follow-up of 4.1 years.
Conclusions:
- The self-expanding Wallstent is a durable and effective option for ureteral recanalization in obstructive uropathy.
- Wallstent implantation provides long-term patency, improving outcomes for cancer patients with ureteral obstruction.
